30071 Ballcentric Plug Valve - Henry Pratt Company

A Tradition of Excellence

With the development of the first rubber seated

butterfly valve more than 70 years ago, the Henry

Pratt Company became a trusted name in the flow

control industry, setting the standard for product

quality and customer service. Today Pratt provides the

following range of superior products to the water,

waste water and power generation industries.

A Commitment to Meeting

The Customers’ Needs

Henry Pratt valves represent a long-term commitment

to both the customer and to a tradition of product

excellence. This commitment is evident in the number

of innovations we have brought to the industries we

serve. In fact, the Henry Pratt Company was the first

to introduce many of the flow control products in use

today, including the first rubber seated butterfly valve,

one of the first nuclear N-Stamp valves, and the

bonded seat butterfly valve.

Innovative Products

For Unique Applications

Though many of the standard valves we produce are

used in water filtration and distribution applications,

Pratt has built a reputation on the ability to develop

specialized products that help customers to meet their

individual operational challenges.

Creative Engineering

for Fluid Systems

Pratt’s ability to provide practical solutions to complex

issues is demonstrated by the following case histories.

Earthquake Proof Valves

Pratt designed and manufactured hydraulically

actuated valves for a water storage application so that

the valves would automatically operate in the event of

earthquakes. This lead to the development of a valve

that will withstand forces of up to 6g’s.

Custom Actuation/

Isolation Valves

Pratt designed and manufactured valves that would

isolate a working chamber in the event of a nuclear

emergency during the decommissioning of armed

nuclear warheads. The valves were able to close in a

millisecond using specially designed Pratt electropneumatic

actuators.

Valves Designed for

Harsh Environments

Pratt designed and manufactured a 144" diameter

butterfly valve for the emergency cooling system at

a jet engine test facility. The valve was designed to

supply water to help dissipate the tremendous heat

generated by the engines during testing.

Through experience, commitment and creative engineering, Pratt is uniquely

suited to provide superior products for our customers’ special needs.

ADVANTAGES OF ROUND PORT VALVES

FEATURE

■ Efficient economical flow

■ Port passes larger solids

■ Port offers less resistance

to slurry, sludge and fluid flow

BENEFIT

COMPARISON TO RECTANGULAR PORTED VALVES

Valves for the 21st Century

■ Better flow characteristics resulting in

less pressure drop across the valve

■ Reduces plugging problems

■ Less erosion, longer service life and

reduced pumping costs
